Abstract (en)
[origin: EP2135732A1] A foamed layer-laminated film or sheet having a foamed layer of a thermoplastic resin laminated on a base material such as a paper or PET, and is useful as a material for producing formed articles such as paper containers, aluminum foil containers, packing films and sheets for containing high-temperature foods, beverages and the like owing to its enhanced heat-insulating property. The foamed layer has innumerable fine elongated foamed cells, and local shades of distribution density of the cells create an appearance of vertical striped patterns on a frosted-glass-like translucent background lending the laminated film or sheet well for use as a material for ornamental articles. The invention further provides a process for easily producing the film or sheet maintaining good productivity at a low cost. The laminated film or sheet includes at least a base material and a thermoplastic foamed resin layer, the foaming layer being foamed at the time of extruding a thermoplastic resin composition containing a foaming agent so as to be laminated on the base material.
